How is your power supply? does it seem like you have to wiggle your cord that connects to computer to make it recieve power?...Many laptops power supply become loose over time form moving the cord around..when it does, the battery has a hard time getting electric power to recharge. Also, you my have other problems with your lithium internal battery that powers your cmos.
Check to see if your power supply is loose and go from there. the power supply is the little hole where you connect the cord to the laptop.
it happens some times dont panic check the switch button is it on or not check the power cord is correctly inserted after that take the battery off wait for 15 mins put the power cord in the laptop turn on the laptop and try to move the lid up and down i hope it will work for you sir.
